XR plug-in management by script

hey all im currently creating a command line build and i need to manually turn on Arkit within the xr-plugin management package. It seems the code to do this though is not a public method so i am at a loss of how to do it this outside of the editor? what i currently have is

Code (CSharp):

1.             string arkitPackage = "com.unity.xr.arkit";
2.  
3.             var buildTargetSettings = XRGeneralSettingsPerBuildTarget.XRGeneralSettingsForBuildTarget(BuildTargetGroup.iOS);
4.             var pluginsSettings = buildTargetSettings.AssignedSettings;
5.             var didAssign = XRPackageMetadataStore.AssignLoader(pluginsSettings, arkitPackage, BuildTargetGroup.iOS);
6.  
7.             if (!didAssign)
8.             {
9.                 throw new System.Exception($"didAssign broke please check package exists {arkitPackage}");
10.  
11.             }

but it throws errors because I have not told the plug-in manager how to load it yet ie this toggle here in the ui
